CLUTCH-OPERATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 503,853, dated August22, 1893.

Application filed May 31, 1892. Serial No. 434,888. (No model.)

land, in the county of Ouyahoga and State of Ohio, have invented certainnew and useful Improvements in Clutch-Operating Mechanism; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My device is especially designed for operating the sliding sleeves oflarge friction clutches in plants where the available floor space islimited, or where it is desired to operate the sleeve from some pointata distance therefrom. In large electric plants as they are usuallyarranged now-a-days every thing is crowded as much as possible in orderto utilize all the allotted space, and there is ordinarily no room forlong levers which might, under different conditions, be employed to movethe great shifting sleeves of the clutches employed.

The chief object of my invention is to provide a comparativelyinexpensive device which may occupy very little floor space, or whichmay be extended to a point distant from the sleeve, but which will givea sufficient leverage to enable one man to move the sleeve and cause theclutching or unclutching of the clutch members.

My invention consists in the construction and combination of partshereinafter described and pointed out definitely in the claim.

In the drawings, Figure 1 is a side elevation of my improved operatingmechanism, and Fig. 2 an end view thereof.

Referring to the parts by letters, A represents the sliding sleeve whichthe mechanism to be described is intended to move.

B B represent two standards which are secured to the floor in properrelation to each other. To the standard B a fork lever O is pivoted. Theupper end of this lever C is connected by the links a a. or othersuitable means to said sleeve A, whereby, as the lever is oscillated,the sleeve is moved backward and forward. A shaft D of any desiredlength is journaled in the two standards B B. To the end thereof nearestthe sleeve a pinion d is keyed, and this pinion engages with an internalgear segment 0 on the lever C. Ashaft E is mounted in a bearing in thestandard B, and projects on both sides of said standard. On one side ofthe standard a spur pinion e is keyed to the shaft E; and this pinionmeshes with a spur segment d keyed to the shaft D. On the end of theshaft E which is on the other side of the standard a large hand wheel Gis secured by means of which the shaft is turned.

It is evident that with the above described construction a very smallforce applied to the hand wheel will move a very large and heavy sleeve.The necessary mechanism occupies only a small amount of space; butbymaking the shaft D longer or shorter the mechanism may be operated fromany desired point.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a clutch operating mechanism, in combination, the two standards B B,the lever O pivoted at one end to the standard B, a suitable deviceconnecting the other end with the sliding sleeve, the internally gearedsegment a on said lever, the shaft D journaled in both of said standardsB B, the pinion (Z secured to said shaft and meshing with a gear segment0, the spur segment 66 secured to said shaft D, the shaft E journaled inthe standard B, the spur pinion e secured to said shaft E and meshingwith said spur segment d, and the hand wheel G secured to said shaft E,substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
